Keep in mind that only the gamescreen area needs to be 4:3 or 3:4, not the bezel itself, to replicate most games. Otherwise, they'll all look stretched.

I think it's a good idea for anyone who uses artwork files to get a grasp of .lay and .ini files because so many people use so many different setups. I haven't seen any singular format that will work well with every game. The important thing is to know how to manipulate the images to make them fit your own setup. I have a rotating TV and most of my games are set up to use up a 9:16 screen in portrait orientation, but if someone is using an old 4:3 monitor, that won't work. Not everyone needs to take it to the rocket science level that Comboman does, but a working grasp of layouts can change your whole experience with MAME. I liked it well enough that I set up my own sort of Rube-Goldberg apparatus to do the same thing with Daphne and other packages.
